Specieaton ofLe'tters Patent.

Application filed October 24, 1919i. Serial No. 332,989.

To all whom t may concern:

l 3e it known that I, VERNON B.' MOORE, a citizen of the United States, residing at Asheville, in the county of Buneombe and State of North Carolina, have invented new and useful Improvements in Machine Construction, of which the following is a specification.

One object of my present sole invention is the provision of a highly useful organized mechanism in a single unit, designed more especially for grinding the bores 0I" the cylinders of automobile internal combustion engines. y y

Another object is the provision of improved means in the form of appurtenances to the grinding unit for `facilitating the accurate alineinent of the unit with cylinders to be ground.

'To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitelyv claimed.

ln the accompanying drawings, hereby made parthereof:

Figure 1 is a view, partly in vertical sec# tion and partly in side elevation oi the inacliine constituting the best practical embodiment oi" my invention that I have as yet devised. i

Fig. 2 isa plan view of the same.

8 is a horizontal section, taken in the plane indicated by the line 3--3 of Fig.

l, looking downwardly.

llg. 4 is a detail plan view of the rotary member of the collector supplying electrical current to the motor.

Fig. 5 is an inverted plan view of the -stationary vmember equipped with contacts Opposed to the collector rings and designed t0 `be connected With a source of electrical energy.

Fig. 6 is a plan view ofthe platefor alining the `Grinding machine with a cylinder to be ground.

Fig. 7 is a detail view of one of the gages Jfor positioning the plate shown in Fig'. 6

Y relatively to the cylinder to be ground; the

invention contemplating the employment of a number of gages of the kind stated, but

with reduced portions of different diameters and adaptedto be socketed temporarily in cylinders of different sizesincidental to the positioning ofthe plate shown in Fig. 6.

Similar numerals of reference designate corresponding pai'ts'in all of the views, of the drawings. The plate 1 shown in Fig. 6 is provided l patented Apr 12,1921.'

with a circular opening 2 surrounded by an 1 upstanding flange 3 of a diameter to snugly fit in the supporting frame 4 of the grind# ing machine or unit.- .Said plate 1 is also provided with a plurality of slots 5 to receivekboltson an engine, so that after' proper adjustment, the flange 3 may be alined with the bore lof the particular'cylinder 'that is to b. interiorly ground. ln positioning the flange 3 in the manner described, a gage 6, such as shown in Fig. 7, is employed; the.

said gage having a reduced portion 7, of a.

diameter to snugly fit in the cylinder, and the upper portion of the gage being of 'a diaineter to fully occupy thellanged opening- 2 in plate l. Obviously after the plate l is positioned with the assistance of the gage 6, the said gage 6 is lifted out ol the cylinder and the opening 2, and then the support 4 isplaced on the plate 1 and around .the flange 3, and is bolted to theplate l and the engine at the' points 8, indicated in Fig. 1. In its opposite sides the support 4 is provided with openings 95 It will also be noted, by reference to Figs. 1 and 3, that the support 4 is provided with an upstand- Y. ing cylindrical portion 10 that is open at its lower and upper end ;--also, that surrounding and fixed to the said cylindrical portionlO- is an annular gear 11.

Movable vertically and also about its vertical axis in they cylindrical portion 10 of the support 4, Vis a hollowr cylindrical body 12 that constitutes an important feature of my invention. At its lower end said body 12 eov body A12 is a slide rest 16, disposed diametrii cally of said body, and adjustable diametrically of the bodyl2 in the said slide rest 16 is a slide 17, designed to be adjusted andA adjustably 'tired 'through the medium of :a

` hand screw 18, that bears in an. upright end portion. 19 of the slide rest.

Mounted on the. slide A17 isA an extended downwardly vthroughl the body 12 and is journaled adjacent to its lower end 22, the shaft 21 is in a; horizontally adjustableV bearing 22 that is4 supported on the body Hange 13, and 1sadjustably fixed to said .flange through .the medium of a screw 23. Below' the' bearing equipped/with a' grinding disk 24 and a fan' 25 to displace grindngs;

the said disk 24 being removably fastened on the shaft for obvious reasons. It will be noted here that through the medium of the screw 18, thel slide' 17, the motor 20 and the motor shaft 21 may be adjustedl to present the periphery of fthe disk 24 to the' wall of the cylinder that is to 'be bored; also, that the screw 23 coperates with the hand screw 18 in adjustably ixing the said parts to hold with a worm 26 for a pu the disk 24-to its work. Above the casing of the motor 20, the shaft 21s equippd ose hercina r set forth, and a o've the vsaid worm 26 the bod 12 is provided with a collector-member rings are opposed to contacts 29 that are 27, aving conductive rings 28, as shown iii Fig. 4. Ihefsaid collector member 27 ro tates, ofcourse, wit the body '12 and its .carried byv an upper `nen-rotatable member l 30,*1`Figs. 1, 2 and 5, and are adapted to be connected in the ordinary welllknownman- .p The rst of said connections includes an ner with a source ofvelectrical ener The stationary member 30 of' the colector 1s mounted on an arm 31; said arm havlng a vertically disposed sleeve 32 that slides loosely.V on an upright guide rod 33, so that `the collector member 30 may be maintained in proper relative position yirrespective of the vertical movements of the cylindrical body 12.

I will now describe the peculiar and advantageous driving connections for turning the cylindrical body 12 about its axis and for 4vertically translating the said body 12.

upright shaft 40 having at its lower end a spur gear 41 intermeshed with the fixed any nular gear 11. The said ,shaft 40 `is journaled in a bracket 42, carried by a ring 43 that is adapted to turn about the upright cylindrical portion 10 of the support 4, and is supported by the gear 11 and suitably retainedl in position. Journaled in the bracket 42 is a shaft 43 on which is a spur gear 44 that enters a vertical groove 45in `-the body 12 and intermeshes with the teeth of the rack 14 in said groove 45. Manif estly the arrangement of the gear 44`in the groove 45 will cause the cylindery 12 to turn about itsaxis with theI ring 43 andthe bracket 42, whenthe said ring 43 is turned about the cylinder portion 10 by rotation lar gear 11. electrical- '.motr 20, the armature shaft 21 .of which 1s.

attended b' p averses4 of the-'shaft 40./and gear 41, and the enf f gagement between the latter andthe almu- The driving connection to translate the body`12jincludes the shaft 43,

the spur gear 44, a worm gear 46 fast on 'the shaft 43,' and a worm 47 fast on the shaft 40 and intermeshed with the gear 46. Manifestly rotationl of the shaft 43 in one direction will bevattended by upward move-f ment of the body 12, and rotation of the shaft ,43 in the opposite direction will bey downward movementA of lsaid body' 12. t 44a the bracket 42 is movable vertically in a groove 44b of body 12 to assist in the turning of the body 12. 1

.As best shown in Fig. 1, the cylindrical body 12 carries a bearing bracket 50 with' A a horizontal arm 51 and an upright arm'52. The shaft 40 is journaled in the arm 51, and in the arm 52 is journaled a horizontal shaft 53 on which is splined a worm gear 54 that is intermeshed with the worm 26. Thus the` .shaft 53 is rotated from the armature shaft 21 of the motor. At its outer end said shaft 53 is equipped with a miter gear 55.

The bracket bearing being carried by vthe slide 17, and said slide being supported on and movablevertically with the body 12, it follows that the shaft 40 must'be capable of vertical movement through the bracket arm 51. Therefore for the transmission of rotary motion to the shaft 40, irrespective of the vertical movements of said shaft, I provide at opposite sides of the gear 55 miter .gears and 61 splined to the vshaft 40 or cdn-venient adjustment and adjustable fixing of the gears `60 andv61, I provide the anguiar lever 7() pivotally.l mounted at 71 on the bearing arm" 52 and having the outwardlyv reaching arms f connected to the circumferentially groove p rtion 73 on the sleeve 74 that is interpose between and xed to the gears 60 and 61.

ItV will be apparent from the 'foregoing that in the practical operation'of niv novel grinding machine or unit, the'machine may be accurately positioned relatively toa cylinder to be ground, and that the grinding .disk 24 may be moved horizontally to place its periphery in engagement with the cylinder wall, and may as readily bev adjustably fixed. It will also be noted at this point upper angular end 62 of shaft 40. For the ized.

that the disk 24 may be nicely adjusted horizontally as the work progresses. Then when the motor is put 1n operation, the eylindri'cal -body 12 will be moved down-` wardly and about its axis at oneand the same time, or if desired, the body 12 may. be simultaneously raised and rotated about its axis. Again when the gears 60 and 61 are neutral-c'. e., both are secured out of engagement with the gear 55--the body l2 may be slowly translated and rotated about its4 axis at one and the same time by hand, through the medium of a crank or wrench applied to the upper angular end ofthe i ent,.'is:
